MACHINE FOR SPONGING CLOTH.

SPECIFICATION forming part of Letters Patent No. 516,945, dated March20, 1894.

Application filed January 28, 1893. Serial No. 460,000- (No model.)Patented in Austria-Hungary May .19, 1892, 110.26.144;

in France November 14, 1892,110. 225,682, and in England December 14,1892, No. 24,156.

To all whom it may concern.-

Be it known that I, THEODOR SARFERT, a subject of the King of Saxony,and a resident of Chemnitz, Saxony, German Empire, have invented certainnew and useful Improvements in Machines for sponging Cloth, (for whichpatents have been granted in England, No. 24,156, dated December 14,1892; in France, No. 225,632, dated November 14, 1892, and inAustria-Hungary, No. 26,144, dated May 19, 1892,) of which the followingis a specification.

This invention relates to certain improvements in cloth finishingmachines, and has for its object to provide a device of this characterwhich shall be simple and inexpensive in construction, effective inoperation and which shall obviate certain defects attendant on otherforms of such machines heretofore employed, all as will be hereinafterfully set forth.

The novel features of my invention will be carefully defined in theclaims;

In the accompanying drawings which serve to illustrate myinvention-Figure 1 is a general front elevation of a machine constructedaccording to my invention and Fig.2 is a side elevation of the same.Fig. 3 is a detail sectional view of the steaming cylinder and Fig. 4 isa corresponding view of a modified form thereof which will be referredto hereinafter. Fig. 5 is a cross section of the steaming or spongingroll detached with its surrounding parts.

In the views A represents a frame of suitable form and strength, inwhich is journaled a cross shaft '1'.

O is a counter shaft bearing the usual tight and loose pulleys n m,together with a friction wheel 0, the periphery of which is inengagement with a second friction disk or wheel 0 mounted on a verticalshaft Q, the upper end of which shaft is provided with a bevel gear q,engaging with a bevel gear (1 on the machine shaft 1", as clearly seen.Mounted on the frame above shaft r and driven therefrom by means ofgears r, r is a second shaft e, on which is mounted the steamingcylinder or roll (1.

Around the roll a, are arranged at suitable points a number of lightrollers 6', e f, f',f f three of which are adjustably mounted in movablebearings as clearly shown, said bearings being arranged in guide-waysand adapted to be adjusted by means of screws 8, 8', collared in theframe as clearly seen in the drawin gs. Over these rollers passes anendless covering cloth or apron 't, which also passes 7 about thesponging or steaming roll a, being reversed over the upper rollers e 6as clearly seen in Fig. 5. This covering cloth is composed by preferenceof felt or other suitably close and impermeable fabric, and serves toprevent too ready passing of the steam through the cloth, as well as tohold the cloth strained on the sponging roll in order to preventshrinkage. The cloth to be finished passes from a reel w, over a tensiondevice composed of the transverse rods Z, Z, over the rollers h, 71/,down over the roller 6, between the covering cloth t and the peripheryof the roll a, around said roll where it is steamed or sponged, up overthe roller e and finally onto the roller or reel 70. Between the rollerse, 6 is arranged a light roller d, which may be heated in order to drythe cloth and to smooth the same after the operation of sponging hasbeen performed. The roll a is composed of an outer perforated drum andan inner cor rugated imperforate cylinder b, both of which are fixed onshaft e and receive and discharge steam through ports e e suitablyformed in said shaft. The outer drum or is supplied with steam forsponging through an inlet tube- 62X (see Fig. 3) which opens into theinterior of cylinder 1) the ends of which 'are open as clearly seen,said cylinder being mounted on spiders on shaft 6 whereby its endsremain open. Thus it will be seen that the steam for sponging the clothpasses out through the open ends of the corrugated and imperforatecylinder 17 and passing through the perforations in drum a reaches thecloth.

In order to prevent the formation of water stains, &c., in the cloth dueto the falling thereon of water of condensation from the steam in thesponging roll, I have provided the cylinder b with inturned flanges 2'at its opposite ends whereby any water which might fall from the inlettube 6 will be caughtand held within said cylinder 1) and in order toprevent the accumulation of such water in said cylinder, I have provideda steam coil 0,

arranged in said cylinder b and receiving a supply of superheated steamthrough ports in shaft 6, whereby such water of condensation as may fallinto said cylinder will be vaporized by the heat from said coil as willbe read ily understood.

In the form of sponging roll illustrated in Fig. 4,1119 construction issubstantially the same, except that the coil 0 is doubled and receivesand discharges steam through ports formed in one end of shaft e, whileat the other end of said shaft are formed ports for the admission anddischarge of steam to and from the interior of said cylinder 1) toefiect the Sponging.

The advantages of my improved finishing machine over other constructionshereinbefore devised are obvious. As stated,the formation of waterstains due to water of condensation falling from the sponging roll ontothe cloth is prevented and by the provision of the endless coveringcloth or apron t, the said cloth is prevented from shrinking While undertreatment,being held securely between said cloth and the drum.

Having thus described my invention, I claim- 1. In a cloth finishingmachine, the c0mbination with a shaft, of a sponging roller consistingof an outer perforated drum and an 30 der having open ends provided withinturned o flanges, an inlet pipe having its mouth arranged within saidinner cylinder and adapted to supply the steam for sponging, and a steamcoil, arranged in said inner cylinder around the mouth of said inletpipe and 45 adapted to contain superheated steam substantially as setforth.

In witness whereof I have hereunto signed my name in the presence of twosubscribing witnesses.

THEODOR SARFERT.
